Hi, I am writing some physics article, and I am including there a SymPy snippet to produce some series (you can see the output in the gist as well):
https://gist.github.com/3615868 And unfortunately, it works with SymPy 0.7.1, but fails in the current master. Git bisect shows that it was broken by this commit: https://github.com/sympy/sympy/commit/0f914e7b29573a82f7267352cfd80089460242ad I am not quite sure what's happening. But if you run my script at this commit, it will hand at the line: f = (2*l+1) / (2*t) * integrate(legendre(l, (1-R**2+t**2) / (2*t)) \ * exp(-alpha*R), (R, 1-t, 1+t)) Is this a supported way of constructing symbolic integrals? I then need to evaluate it for particular numeric "l", so I just use for example: f.subs(l, 4).doit() I like that it keeps the code like the mathematics. I am asking before the release, because it'd be sad if people could not run the code after the article is published (I am referencing a sympy 0.7.1 so at least that version will work). I'll be happy to rewrite it of course, if the above way is not supported. Ondrej -- You received this message because you are subscribed to the Google Groups "sympy" group.
